IMPROVEMENT IN EARTH-CLOSETS.

Specification forming part of Letters Patent No. 162,116. dated April13, 1875 application filed April 9, 1873.

To all whom it may concern:

Be it known that I, MrLLINeroN HENRY SYNGE, of the United Service Club,Pall Mall, London, England, Major General Royal Engineers, have inventedcertain Improvements in Deodorizing Apparatus, of which the following isa specification:

This invention relates to improvements in apparatus for deodorizingfecal matters, either prior or subsequently to discharging them into areceptacle, where they may be allowed to accumulate for a time withoutdetriment to health or creating any inconvenience. The inventionconsists in the use, in combination with a self-acting deodorantdischarge-apparatus, of a series of intercepting pans, applied to acloset and capable of receiving an intermittent axial motion, by meansof which empty pans are brought in succession into position, and whenfilled are caused to discharge their contents into a receptacle below.

In the accompanying drawing, Figure 1 shows the improved apparatus intransverse vertical section. Fig. 2 is an elevation of the left-handside of the apparatus 5 and Fig. 3 is a crosssection of the same.

In these figures, A is the closet-seat, and B achamber at the backthereof, containing granulated charcoal or other suitable dry deodorant.This chamber is closed at bottom by a measuringwheel, O, whichdischarges the deodorant in measured quantities down the chute. It willbe seen that in about the position of the pan of the ordinarywatercloset with respect to the seat A, a four-sided rotating drum, D,is mounted horizontally. The perimeter of this drum is formed withconcaves, and the ends of the drum are fitted with disks, and thus aseries of four pans, or less or more, is constructed, which pans areintended to receive in succession a charge of deodorant and fecalmatters. The spindle of this drum D I fit at one end with aratchetwheel, D, Fig. 2, the teeth of which correspond in number withthe number of the pans, and at the opposite end of the drum-spindle Ifit a chain pulley, D which is intended, as the drum rotates, to operatethe measuringwheel G of the chamber B, containing the powdered charcoalor other deodorant, and discharge a suitable proportion thereof into theuppermost pan. Mounted loosely on the drum-spindle and adjacent to theratchetwheel, is a bar, E, which carries a pawl or catch, F, that takesinto the teeth of the ratchet-wheel D This bar is connected loosely tothe rod G of the pull-up handle of the apparatus, which rod is weightedto bring down the handle when the latter is released and force forwardthe catch, which will thereby impart a quarter revolution to the drumand tip the materials deposited upon the uppermost pan, OK that pan,down an adjacent shaft or trunk, H, leading to a receptacle, I. Thematerial, in falling from the shaft into the receptacle I, below, might,if no special provision were made, be liable to accumulate ina heapimmediately under the shaft. In order, however, to distribute it overthe bottom of the receptacle, I cause it to fall onto a distributor,consisting of a cone, K, with a broad base and concave sides. If thisdistributor is made with a smooth (by preference, glazed) surface, thefalling materials will be shot toward the extremities of the receptacle.The measuring-wheel 0 consists of four radial leaves, made fast to apair of disks or circular end plates and constituting therewith fourmeasuring'chambers. Keyed to the axle of the measuring-wheel is a chainpulley, for receiving an endless chain, G which passes round the pulleyD and thus connects the measuring-wheel and drum together. The drum D,as it is turned round by the action of the pull-up handle in thedirection of the arrow, discharges the contents of the uppermost pan andsimultaneously the measuring-wheel G will receive a partial rotation.The effect of this will be to cause a momentary discharge of charcoal orother deodorizer from the chamber B into the pan that has just beenbrought into position, and thereby to prepare the apparatus again foruse.

It will be understood that the drum may be provided with any desirednumber of pans, and that the mechanism" for rotating it and themeasuring-wheel of the deodorant chamber, may be indefinitely variedwithout departing from the nature of my invention. It

will also be obvious that instead of using the pull-up handle as themeans for imparting motion to the drum and delivery-valve, otherwell-known or equivalent means used in connection with Water-closets,for transmitting motion, may be employed.

Having now set forth the nature of my in- Vention, and explained themanner of carrying it into effect, 1 wish it to be understood that Iclaim- The combination of the rotating pans with the measuringinstrument for supplying the charcoal or other deodorant to the pans, asthe sameare brought up into position for use, substantially asspecified.
